Rousseau, Michel. "Aspects juridiques de l'organisation des marchés agricoles." Toulouse 1, 1989. http://www.theses.fr/1989TOU10030.
Повний текст джерелаThis analysis is about substructure, delimitation and finalities of the organization of agricultural markets. Many organisms are used by this organization, but they are inefficient to concentrate the supply. So, they have no positive significant results concerning the farmer's increase of income, and the parity wanted by the authorities since 1960. The intervention of the government must be modified channels and real must be created to organize the agricultural and food markets. It's absolutely necessary in a distinct coherent juridical framework

Повний текст джерелаThis thesis deals with the contractual relations between the French agency and aerospace manufacturers (institutional markets). The first chapter presents the characteristics of institutional markets: participants' objectives, industrial organization forms and the nature of information between the agency and the manufacturers. The analysis permits to extract the problematics of the next chapters. The first part of chapter two reveals that is can be optimal for the agency to give the second market to the incumbent of the first market rather than second sourcing. Nevertheless, the research and development effects mitigate the interest of second sourcing. The manufacturers and the agency, when establishing the price of a unit of new equipment, don't know its (social) value. Sometimes, they commit to lower price for the potential production of a second unit. The second part studies the price evolution of a good whose value is unknown before it is consumed. The result depends on the assumptions on the price contingencies and the commitment nature of product and customer. The third chapter proposes a model of risk sharing between a risk neutral principal and a risk adverse agent -the manufacturer. The chosen approach considers that the agent can decide which states of the nature that the principal will audit. An empirical test of the model is done on agency-industrial contract data related to artificial satellite building

Повний текст джерелаThis thesis develops a procedure to analyse differentiated product markets and provides an application to the market of household telephone equipment in France. We construct a structural microeconomic model that takes into account the main features of the market under study. An empirical analysis is then provided with the help of econometric tools. In the first part we describe the market under study and the available data. In the second part a survey of the literature is done in order to stress on the pros and cons of the approaches already used. In the last part, we set the economic and econometric framework and provide empirical results on the functioning of the market under study
Baudin, Pierre. "La politique des marchés agricoles de la Communauté européenne." Paris 2, 1992. http://www.theses.fr/1992PA020100.
Повний текст джерелаThe european community has implemented a common organization for agricultural markets based essentially on a common prices policy. The application of common prices to a heterogenous structure of farms leads to an acceleration of agricultural dynamics. These dynamics are characterized by a growth of supply, due to the increase productivity and investment in large farms, which is faster than the growth of demand and the adjustment of the factors of production. To face the surplusses created by this evolution, the community has, firstly, used all the instruments for market management up to the limits of their possibilities and then, during the 80's, modified the forms of common organization for some agricultural markets. The original characteristics of the present study lie in the demonstration that the evolution from one form of market organization to an other follows a very precise pattern. This evolution tends, on the one hand, to allow the market a higher degree of freedom and, on the other hand, to modulate public intervention with direct aids to income. These direct aids are targetted on farmers rather than being proportional to production quantities. The current proposals for the reform of the common agricultural policy are in line with this evolution
Kouassi-Mauger, Eliane. "La dynamique des marchés de produits vivriers dans l'espace urbain d'Abidjan." Nantes, 2004. http://www.theses.fr/2004NANT3007.
Повний текст джерелаThe expansion of food markets in Abidjan come within the framework of a fast and recently decentralized urbanization. Different in their size and in the way they set up, the markets have conquered new territories and spread widely over the city. So urban consumers have access to abundant and various provisions. Highly structured trade networks control the supplying of the business capital of Côte d'Ivoire. Besides their supplying function, the markets open the way to modest but regular source of income for women. Moreover, they reinforce the urbanization by creating new buildings and livening areas up. New policies of market construction reveal the interest the authorities take in these spaces. However privatization raises social and town-planning problems
Mbombo, Raphaël. "Pertinence économique de la stabilité des marchés agroalimentaires." Master's thesis, Université Laval, 2019. http://hdl.handle.net/20.500.11794/34074.
Повний текст джерелаThis study focuses on the economic relevance of stable agricultural markets. To do this, we explored the explanations offered by the economic literature on the dynamics of agricultural prices, including the effects of price volatility on the optimal allocation of resources at the producer level and the efficiency of markets. In addition, the effects of price stability, associated for instance with supply management, are qualitatively assessed by surveying stakeholders of the Quebec's agrifood sector. Some economic literature considers that the risk and uncertainty associated with price volatility negatively impact the economic optimum. Mini-case studies and the results of our survey seem to confirm these effects. Our results also suggest that farmers attach great importance to price stability in general. Predictability of prices facilitates the optimization of production and the financial management of farms. Stable prices, which reflect the cost of production, contribute to the sustainability of farms as they adequately pay farmers and their assets. Hence, they are an incentive for investments and growth projects that, in turn, benefit input and service providers, according to key stakeholders. In the end, the stability of the margins associated with supply management is seen as a positive contribution to the economic vitality of Quebec villages, as well as to the presence and diversity of agricultural production models.

Повний текст джерелаThe law of 11 February 2005 enables a change about the way we perceive disability. Alike for models and definitions development, the associations of People With Disabilties (PWD) keep fighting for accessibility for all of them. It’s within this context that our researches claim the benefits of innovating design integrating the needs of these users that indutrials consider as a niche market. As PWD are approximately 50 millions European people worth, can this market be still considered as a niche one? The analysis of the assistive technologies market points up a full scope for an innovation process focused on PWD needs in order to overcome existing lacks. To define the characteristics and the needs of these target users requires to understand and characterize what creates a disability situation. Some PWD specific needs are already at the root of inventions and technological advances used by a majority of people today (e. G. Remote control, mixer taps, voice recognition, etc. ). We’ll try to demonstrate through experiments leaded in partnership with the French Neuromuscular Diseases Association that knowledge of target users needs can be considered as a potential source of innovation for everybody

Повний текст джерелаFrom the middle of the 17th to the end of the 18th century, the French empire had a dominant position in the market for indigo in Europe. From Saint-Domingue, indigo was imported in France and then reexported to the Mediterranean and North European countries. Indigo was a tropical dyestuff that was widely used in the textile industry on cotton, silken and woolen textiles. The dyeing industry was one of the most innovative sectors in the textile industry, closely connected with new inflows of tropical dyestuffs, technical exchanges with Asia and the Americas and the birth of modem chemistry. This dissertation aims at showing how in the long distance trade, producers and users of indigo were able to communicate, considering that indigo was a highly heterogeneous dyestuff

Повний текст джерелаOur evaluation of public prrocurement policies takes into account market structure, the nature of transactions and the organization of the purchasing process, the product life cycle, and the conditions of implementation of the policy. Government purchasing produces important effects on industry structure, conduct and performance. The main result of our empirical and conceptual analysis is that public purchasing can be a relevant instrument of industrial policy under specific conditions, in particular at the beginning of the product life cycle, in an open industrial setting characterized by radical uncertainty, when the market power of the government is sufficient and when government behaves as a risk-taking quality leader. Our empirical analyses deal with federal, state and local procurement policies in the united states and comparisons with canada and france, in particular in the computer industry, supercomputers and semiconductors, railroad transportation equipment, environmental clean-up, aerospace, and machine tools
Hugou, Brice. "Les marchés financiers de matières premières agricoles à la lumière du droit des contrats." Thesis, Nantes, 2018. http://www.theses.fr/2018NANT2032/document.
Повний текст джерелаFood security requires that each inviduals can obtain food in sufficient quantity and quality. This means that food prices must be neither too high for consumers nor too low for producers. After the food riots that started in 2008 following the increase of food prices, many concerns have been expressed about the impact of financial makets toward this rise. In order to shred some light on this issue from a legal point of view, this work aims to review differents aspects of the developpment and functionning of financial markets. Special attention will be given to the contracts which are used to into financial opérations Indeed, the legislator reunited all of the various financial contracts under the same legal qualification, without regards for their underlying. However, non financial commodities are different from financial commodities as they can lead to a physical delivery, and be regarded as commercial transactions or financial operations. Thus, they should get an autonomous legal status
Zemmouri, Karim. "La consommation des produits financiers." Thesis, Orléans, 2011. http://www.theses.fr/2011ORLE0001.
Повний текст джерелаIf consumption, in the economic sense, is the final stage of the production and distribution of goods, it is perceived in a legal sense, as the starting point of another process linking the consumer to professional. This phase is the starting point of a report which gives rise to obligations which are all professional fees for the consumer.Since the beginning of the particular 90s, an attention is devoted to protection, through some measures specific to the financial law, including the regulation of financial markets, supervision of providers investment services, and other provisions that tend toward a reconciliation of the provisions enshrined in the consumer law including the regulation of canvassing, measures to provide protection in the marketing of products and services Financial distance, enhanced disclosure requirements owed by the broker and the extension of its obligation to counsel.The legal analysis of the consumption process of financial products supposes the combination of all these elements. On the one hand, before and during the formation of links, governments attempt to restore balance in relations between professionals and consumers. The latter being deemed economically weak, do not have the same information on financial products and services are sought by various means and technologies they have no control, and must make choices between various products, and more complex. On the other hand, during the execution of services, in addition to commodity risk, or non-performance of contractual obligations, other risks may arise from failures in market functioning and behavior of its actors. Therefore a means of strengthening consumer protection is needed to overcome the shortcomings of current means that they have to obtain compensation and seek compensation

Повний текст джерелаWe focus here on the consequences of the CAP reforms which have progressively replaced the European price support scheme by a system of payments more and more decoupled from production and prices, and on the opportunity for a new form of public intervention to stabilize agricultural markets. From the different points of view expressed in the economic literature, it appears that some frameworks, more sophisticated than those currently available, are needed to study this question. Those frameworks should notably account for dynamics and the form of agents' expectations. We thus develop a dynarnic Computable General Equilibrium model including the inter temporal decisions of economic agents and allowing the representation of different expectation schemes. Our simulation results show that endogenous market fluctuations, due to expectation errors from economic agents, can arise but are limited by many feedback effects. These results also reveal that, if expectations are imperfect, a gradual implementation of policy reforms is preferable to an immediate one because, in that case, agents have time to adjust their decisions according to market news. Finally, we show that even if stockholders are not fully rational, their behaviours tend to stabilize agricultural markets. However, a public intervention aimed at increasing stocldtoldings is not suitable because it can, in a sense, scramble market signals given to agents, and thus increases markets volatility

Повний текст джерелаIn this thesis, the author discusses three different dynamics of commercialization that underline alternative forms of production and consumption in the case of seafood market. First, the dynamic of the supermarket industry and its suppliers is described, concentrating on the nature of their exchanges and their impact on the quality of the product. Next, the opposite dynamics is discussed. The actors of this market are redefining the nature of their exchanges in organizing their relationships to qualify their products. At last but not least, between them, the merchants accept to behave more foreseeably. In this more structured market, transactions rely on long term relationships and quality is stabilized. The author concludes that the seafood market evolution and regulation are directly influenced by the nature of the product and the nature of the merchant relationship

Повний текст джерелаThis last decade international trade literature is extensively based on heterogeneous firms literature. The seminal paper of Melitz in 2003 The impact of trade on intra-industry reallocations and aggregate industry productivity» allowed the development of rich theoretical models considering firm level decisions. This dissertation focuses on two points that were not considered in the original Melitz model: the role of location within a country and of transport modes on international trade. This dissertation considers the access to international markets of French Agrifood firms. Agrifood sector is the second industrial sector in France in terms of trade surplus. It is divided in two parts. In the first part, the impact of the local environment on the international competitiveness of firms is studied. It aims at evaluating if the proximity with other exporting firms helps firms to export. The fact that a firm's location choice is not random is taken into account here. In a second part the impact of transport modes on trade is analysed. The question of the differentiated impact of modes on aggregated trade level is considered. An estimation methodology is proposed. Then the transport mode choice at the firm level and its implication on its export performance are addressed. The empirical analysis uses disgregated database gathering detailed information on firms (EAE and Custom services data)

Повний текст джерелаThis thesis focuses on the way one can make very short run predictions of spot oil and petroleum derivatives prices. Broadly, there are two issues of interest: the autoregressive expectations and the price discovery role of oil futures prices. In the first part we examine two different forecasting methodologies: technical analysis and time series modelling. Our empirical results show evidence for predictive power of the moving average rule on spot oil prices. On the other hand, the statistical properties of these prices led us to apply arch/garch methodology. The empirical results show, among other things, the existence of mean and conditional variance "day of the week" effects. The second part of this thesis is concerned with the informational role of oil futures markets. We first describe the functioning of oil future markets. Then we test the informational role of the basis (difference between the spot and future prices). In the last chapter, an equilibrium model under rational expectations and asymmetric information is constructed to show that the equilibrium future price transfers informations. Empirical tests show that daily brent future prices doesn't contain interesting informations on the evolution of daily dated brent price. But contain useful information to predict the evolution of dated brent price volatility

Повний текст джерелаAmong the measures adopted to balance the agricultural markets, the community legislator chose to charge the producer for all or part of the costs resulting from the selling of agricultural surplus by the eec, establishing financial contribution in the common organisation of markets (com) of milk and dairy products (1977) and of cereals (1986). They were modelled on contributions to the production of sugar and isoglucose set up from the com creation. "unity and diversity" link these contributions : unity, because all of them are based on article 43 eec and implemented according to much the same rules ; diversity, because they follow different aims (account purpose to guarantee the sector's budgetary autonomy for sugar and isoglucose contribution, instrument of penalty allowing only to decrease the costs which lay on the community budget for coresponsibility levies), and because only sugar and isoglucose contributions which are correctly budgeted on the basis of article 201 eec, become proper resources, while coresponsibility levies, listed on the basis of article 43 eec, remain "intervention measurtes with economical finality" budgeted as negative expenses, interfering with basic legal rules

Повний текст джерелаThis thesis is in the area of corporate finance and focuses on the impact that diversified institutional investors have on the competition in the product market of portfolio companies, also through the analysis of their votes on proposals in the general meetings of portfolio companies; it also analyzes the impact of the environmental and social funds on the corporate governance of portfolio firms. Chapter 1 investigates the relationship between common institutional ownership of firms in sectors along a supply chain and product market competition and provides evidence that the anticompetitive effects are only present in more downstream sectors. Chapter 2 investigates the role of Environmental and Social (ES) funds in corporate governance through exit and provides evidence that their asset allocation constraints regarding the ES profile of portfolio firms reduce their ability to influence portfolio firms through the threat of exit. Chapter 3 analyzes the voting records of institutional investors to understand if their voting behavior is aimed at internalizing externalities among horizontally and vertically related portfolio firms and finds limited empirical evidence

Повний текст джерелаSince the beginning of the eigties, the falling down of the food resources is one of the major economic problems in West Africa. For supply side economists, governments' interventions had largely contribute to increase this deficit; for them, the reduction of the supply-demand gap could only rely on the market economy. The Togo’s case shows effectivly that, since the beginning of the century, a private trading system was able to feed urban areas. But the efficicy of this structure is limited. It's not able to manage completly the uncertainty which is inherent in any imperfect market system. So, the improvment of the market efficiency depends on the ablity of the state to rule the market economy of staple foodstuff. But, the improvment of market efficiency of the trading system and incentives in terms of prices may be not sufficient to encourage the transformation of the structure of production, since this rural society is still and mainly a subsistence oriented economy

Повний текст джерелаThe Agricultural Agreement of the Uruguay Round, 1994, was a real change in the liberalization of agricultural trade. Negotiations go on and generate new reform of the Common Agricultural Policy and adaptation of instruments used in the United States. In order to measure impacts of instruments of agricultural policies, a world econometric model which represents production, consumption and trade of agricultural products, is developed. The originality of this project is the explicit representation of instruments of agricultural policies. The modelling of export and import functions allows to distinguish export instruments (subsidy, credit, food aid) and import instruments (tariff, import quota). Simulations of agricultural policies (total or partial liberalization) are implemented

Повний текст джерелаIn economy, the competition analysis among firms have a significance importance because of the complexity of some elements. This thesis examines the strategic interactions on differentiated markets in general equilibrium while proposing the public policies to reduce the distortions due to the imperfect behaviors. This thesis takes into account the differentiation of products in order to obtain the new conclusions and/or to extend those existing. We thus pursues two objectives. Fisrt, the construction of a model of imperfect competition on differentiated markets in a general equilibrium framework. Second, the evaluation of the consequences of the model in terms of economic policies. At beginning, we use literature review to tackle successively price mechanisms in strategic market games, product differentiation concepts and game theory models dealing with strategic interactions in order to model imperfect behaviors. This led in chapter 2 to the symmetric Cournot-Walras equilibrium concept on differentiated markets where we assign to each economic agent a finite vector of differentiation coefficients which expresses the agent's love for diversity. Following the differentiation model, chapter 3 offers tax policy mechanisms to control losses due to perfect behavior of firms. From the analysis, it appears that some examples illustrate that the differentiation model admits a trivial equilibrium which is nice and the price and allocations of symmetrical Cournot-Walras equilibrium on differentiated product, under certain conditions, converge towards the Walrasian ones

Very often, knowledges and sciences are crossing to emerge innovation. Chaos theory and psychoanalysis have been used to complete marketing. Micro innovation is the thesis foundation. Micro innovation alters lightly global supply. But it disrupts the sensorial point of view of consumer, one of key to win new products launch. It proves that marketing theory can be renewed by new tools (analysis and chaos theory). Micro innovation is showing a schema of peoples who can consume old brand. This paper tries to prove to marketers and managers that micro innovation can be used in beauty and cosmetic markets

Повний текст джерелаThis thesis examines in three empirical essays levels and changes of CDS spread related to largest European companies. In the first chapter, we aim at identifying most important variables that drive CDS spreads in normal market conditions We suggest a list of new microeconomic variables and we find there exist some remaining sector wide common factors. In chapter two, we examine credit risk spillovers of CDS and equity markets under extreme conditions. To this end, we implement among other the very recent CoVaR technology of related entities. We also find here indirect evidences that sectors govern the behavior of individual CDS. In chapter three, we finally undertake a number of event studies on CDS and Equity daily data making use of hand-collected credit rating changes. Among other things, we evidence that both CDS spreads and equity prices move as the rating changes but also that movements differ according to upgrades, downgrades, succession and turnovers

Повний текст джерелаThis thesis explores theoretical links between economic integration and firm strategy. In a market structure defined by oligopolistic behavior and vertical product differentiation, two kinds of firm strategy are studied. First, differentiation strategy is analyzed considering both a segmented and integrated market environment. In each case, the impact on consumer surplus, quality supplied and firm profits is analyzed given a decrease in transport costs. Second, Collusion and M&A strategies are studied. The aim of this second part is to demonstrate how economic integration influences firms to collude or merge. Finally, this thesis concludes that economic integration can have counterintuitive effects. It shows that firms develop strategies to offset a more competitive economic environment which may lessen global welfare

Conclusions turn towards the use of a salesforce which comes up to buyer 's expectations, the use of a formal or informal distribution network to assure the geographical expansion of the firm and the exploitation of "word of mouth" on markets.

Повний текст джерелаFollowing the financial crisis of 2007, a set of regulations was implemented, including EMIR in Europe. Among the obligations arising from this text, there is an obligation to declare to the regulatory authority all OTC transactions. The goal is to increase transparency on OTC markets. My objective is to demonstrate that this is not actually the case. For that, I explore two main axes. The first one concerns the implementation of the reporting obligation and the analysis of this data by regulators. For this purpose, I use the public data on this issue and also the private data from my work. The data are relatively well reported but not fully exploited by the regulatory authorities. The second axis is more theoretical. Information does not necessarily lead to transparency. The symmetry of information and trust between OTC’s participants are the most important

Повний текст джерелаThis thesis deals with the economic analysis of the long-term security of supply in liberalized electricity markets. The electricity reforms that lead to an increasing integration of electricity markets, as well as the recent renewable promotion policies, add two new issues to ensure long-term security of supply which are the research axes of this thesis. The first research axis shows that the effectiveness of different long-term security of supply is necessarily influenced by the integration of electricity markets based on the conventional perspective of the effectiveness of competition by market integration. We rely on a formal analysis in investment dynamics in two integrated electricity markets to show how the lack of harmonization between local adequacy policies may lead to undesirable side effects in regional electricity markets, which has implications for the effective functioning of national markets. The second research axis shows that large-scale wind power development based on renewable promotion policies disturb the long-term equilibrium creating negative externalities for investment in conventional generation and for long-term security of supply. This thesis shows as well that capacity mechanisms can compensate for the externalities of large-scale wind power development. This compensation takes the form of a penalty for the low contribution of wind power to system long-term security of supply, giving it a much lower value. This compensation takes the form of a penalty for the low contribution of wind power to system long-term security of supply, giving it a much lower value

Повний текст джерелаCounterfeiting luxury products are a worldwide problem that causes many challenges within economic change. Counterfeiting is one of many unfavorable features of globalization, which is a rapidly growing phenomenon with considerable economic and social repercussions. It is obvious that the spread of the phenomenon and its inevitable consequences are detrimental to the competitiveness of enterprises, the health of citizens, national economies, States and international organizations that have not remained inert but have adopted measures for appropriate regulations to deal with the urgency. A series of rules are thus proliferating to regulate the market. By having its very nature immersed, in order to protect individual and collective interests worthy of protection interests of various natures and not only of strictly economic nature. It is not easy to reduce to a definition of a phenomenon such as counterfeiting, which seeks to escape official investigations and can be detected in all sectors of the contemporary economy. To achieve this, the concept of economy not directly observed has been introduced, it also includes the illegal and informal economy. During my research I analyzed counterfeiting in the luxury fashion market and how this phenomenon is engendered and developed by analyzing mainly the Moroccan case. Starting from the definition of counterfeiting and its characteristics, I will analyze the luxury market, the consumer and the main brand strategies. The research will provide interesting avenues for developing recommendations to combat the phenomenon of forgery and prevent fraud

Повний текст джерелаThis thesis offers a reflection on the link between the internal functioning of the firm - and especially the staff management - and its market behavior as to the quality of products, through the analytical framework of the convention theory. We have therefore chosen to follow three tracks, to demonstrate together the reality and the complexity of this man-product matching. . The wages policy of the firms may have consequences on the quality of the product. We begin with models that have integrated non-economic concepts (equity theory). Still the consequences of these policies on quality mostly emphasize the importance of another issue: the organizational commitment of the wage-earner. . A policy of products can in turn, weight on the labor force management. Previous empirical studies help stress the consequences of introducing a new product on the internal organization of the firm. . We open on to a thorough study of an original model of market, which takes into account, in an especially compact way, the policies of staff management and that of quality. Seen through the usual criteria of consistency and pertinence, this model may be considered as satisfying fully the first criterion, and less so the second one. Nevertheless, a review of this model in terms of convention, added to the empirical study led in the sector of road transport; prove the relative pertinence of this approach. Thus, starting from a seemingly anecdotal issue, one ends up questioning the market as seen by the economists

Повний текст джерелаAs in almost all SSA countries, the majority of the Senegalese population is rural. They earn their livelihoods from agriculture or activities that depend on it. Paradoxically, the public investment in agriculture remains very low, while food insecurity is progressing. To deal with food problems, the government multiplies announcements of agricultural policies, which are almost never followed up, because not based on specific and rigorous studies. Instead of policies, there are mostly management strategies cyclical food crises. In this context, we have sought to understand the strategies developed by the peasantry, the dynamics that drive family farms to reduce food insecurity in rural areas, and to what extent they can contribute to food sovereignty Senegal. This question calls for that of access to adequate food and that of its production. Thus, through our study we have entitled "Farming dynamics, food sovereignty and global market for agricultural products: the example of Senegal”, we try to answer a series of questions: 1. How do Senegalese farmers produce the goods needed to feed and care for their family? 2. How are Senegalese farmers organized around issues of rural life? 3. What is the influence of the world market of agricultural products and its rules established by the World Trade Organization (WTO) on the availability of and access to food? How do imported goods compete with food products that can be produced locally? We have devoted the first part of our study to the production process and its evolution. Apart from weather conditions, effective control by farmers of means of production and land tenure, largely determines the volumes of agricultural and food products as well as their access. The second part analyzes the emergence and evolution of modes of peasant organization and discusses their influence on the satisfaction of food needs and directions of public policy in agriculture. Finally, in the third part, we have tried to measure the impact of international trade rules on local production of agricultural goods and foodstuffs. This work has enabled us to draw some conclusions. The majority of farmers in Senegal can no longer produce the amount of basic foods needed to feed and support their families. The means of production have changed relatively little in recent decades, although animal traction and the introduction of new materials have greatly improved the conditions of production and reduced drudgery. The production tool has deteriorated. It is old and what is left survives only thanks to the ability of rural blacksmiths. Traditional knowledge and knowledge of weather condition the choice of crops grown and acreage devoted to them when they are available. Research in agriculture has yielded certified seed varieties adapted to soil and climatic conditions. But it remains ineffective in that the means for concretely applying its results are absent and the peasants have no control over it. The question of land remains subject to trial and error due to its complexity, traditional beliefs and practices in this area do not yet seem ready to give way to modern rules, or if necessary, adapt to them. More and more severe conditions felt primarily in the food sector have highlighted the capacity of the peasantry to adapt. For each new situation causing additional problems, novel solutions are devised and implemented by farmers, enabling them to adapt in an unexpected manner. Farmers' ability to take charge of their own concerns were highlighted by the emergence of organizations, groups, associations and unions throughout the rural areas of Senegal. As far as international trade in agricultural products is concerned, the weakness of the Common External Tariff (CET) of ECOWAS has resulted in increased volumes of imports of goods that can be produced locally. WTO rules, based on an ultra-liberal conception of the market, are more detrimental to West African agricultural and food products. By strengthening their human resources through legislation, more vulnerable countries such as Senegal, can, however, exploit the clauses that allow them to better protect local production. More globally, unless agriculture is removed from WTO agreements, it is possible to claim with ECOWAS, the implementation of another agreement on agriculture that would redefine dumping so as to protect the most vulnerable countries

Повний текст джерелаThe purpose of the thesis is to examine market organization processes in a context of high-Ievel uncertainty and ambiguities on the nature of exchanged goods. Such "uncertain" markets are said to have brought the idealtype of fordist labor exchange to an end and replaced it by brief and fleeting relations with multiple employers. The cases of French "intermittent" actors and free-lance journalists are here investigated in order to question this hypothesis. Economic sociology provides tools to carry out the analysis of these professional worlds. Eventually, the examination of markets through the lens of exchange relationships is proved relevant. These relations first reflect market structures. The attempts to perform their social constructions, with various outcomes in these worlds, reveals patterns of segmentation-related market organizations. Temporalities of exchange relations may also be understood with reference to the position employers hold in a system of linked markets and to the degree of confusion regarding the nature of exchanged goods -either labour or products. Exchange relations also shape markets. Especially, uncertain markets host at least two relations regimes and the more individuals are committed in recurrent relationships, the more competitive constraints loosen: predictability and organizations are then brought into individual activity. By blurring the boundaries between organizations and markets and making their structure more complex, the existence of such an expected relations regime also raises questions about the very market structures and complicates the design of market segmentation

Повний текст джерелаThe thesis objective is to price credit derivatives such as synthetic CDOs by using advanced quantitative methodologies. We describe the standard market model used for the pricing of synthetic CDO tranches. We then proceed to illustrate the limitations of the standard approach and introduce a new methodology using Normal Inverse Gaussian (NIG) distributions and historical correlations. We compare both approaches in terms of pricing and hedging capabilities and can deduce that our approach is more accurate on both a theoretical and empirical basis. We then extend our research to CDO^2 and introduce two new methodologies for pricing this type of structures. We aiso study the opportunities offered by hedging standardized tranches. We can then conclude that significant model and correlation risks exist in the credit derivatives market. These risks should be taken into account with the credit risk in these types of structured deals
